Listen here. You are a liar and a muppet!! Please provide a link for any other Scraper that states it can only operate at a maximum grade of 5%. You are so far gone it's not even funny. Regardless of that any way I have witnessed with my own eyes (not on a computer either) Cat scrapers basically level almost the entire Northern coastal strip of Perth from large hills into relatively flat residential estates.

and straight from the Cat website in regards to how this argument started in the first place "Working together, push-pull scrapers can provide the lowest cost per meter (yard) for many applications."

Clown!!
